Taxes in Los Angeles

California levies the highest top marginal state income tax rate in the US at 13.3% (nine brackets from 1% to 12.3%, plus a distinct 1% Mental Health Services Act surcharge on income over $1 million), and this record states that plainly rather than letting Proposition 13's comparatively moderate property-tax mechanic imply California is broadly a low-tax state.

California's Progressive Income Tax Reaches the Highest Top Rate in the US

California's income tax runs nine brackets from 1% to 12.3%, plus a distinct 1% Mental Health Services Act ('Behavioral Health Services Tax') surcharge on taxable income over $1,000,000 -- a threshold applied the same way regardless of filing status (NOT doubled for joint filers) -- producing a real 13.3% top marginal rate, the highest of any US state. This is a real, meaningful, and current cost for higher earners specifically, and this record does not understate it.

Proposition 13 Property Tax: A Real, Distinctive, and Purchase-Date-Dependent Mechanic

As detailed in full on the property-taxes topic page, Proposition 13 caps a property's taxable assessed value at its purchase price (growing at most ~2%/year until resale), producing a genuine and often dramatic gap between long-time owners and recent buyers. This is a real, comparatively moderate mechanic for long-time owners specifically -- but a recent buyer pays tax on the FULL current market value, and LA County's effective rate (1.1%-1.5%) still applies to that full value.

No General Statewide Sales Tax Exemption -- California's Base Rate Runs Above Most States

This pass did not independently confirm the current specific combined state-plus-local sales tax rate for Los Angeles specifically, but California's statewide base sales tax rate (7.25%) is itself among the highest in the country before any local add-ons, which push actual rates in most LA-area jurisdictions meaningfully higher. Confirm the current combined rate for a specific LA-area address directly, since city- and district-level add-ons vary.

A Genuinely High-Tax State Overall, Not Offset by a California-Specific Property-Tax Discount for New Buyers

Unlike Oregon's Measure 50 (covered elsewhere in this project's Pacific Northwest coverage) or a genuinely low-property-tax state, California's Prop 13 discount specifically benefits LONG-TIME owners -- a recent LA buyer gets no comparable break, paying both the area's real effective property tax rate on full market value AND California's real, highest-in-the-nation income tax rate. This record states this combination plainly rather than letting either mechanic's individual nuance obscure the other.

Property Taxes and Insurance: Pointers to Full Detail

Los Angeles property taxes (LA County's effective rate, Proposition 13's assessed-value mechanic, and Proposition 19's portability provisions) are covered in full on the property-taxes topic page rather than repeated here, while California's real, current statewide homeowners-insurance crisis is covered on the homeowners-insurance topic page.
